The migration from hardware-defined radios to software-defined radios corresponds with the move from analog radio systems to digital radio system. In the past, the rise of microprocessors enabled communications engineers to develop a new way to transmit information from one place to another. These digital communication systems provided some key benefits over the existing analog communication systems. Despite the advantages, however, both analog and digital communication systems still exist today. Analog systems are still useful for some applications and digital systems will never be able to completely replace analog systems. Similarly, the advantages of software radios may allow them to overtake hardware radios in many situations throughout the coming
years; however, the simplicity and dependability of hardware radios will ensure these
radios continue to exist, as well. Just as radio systems once went through a phase of
converting from analog to digital, radio systems today and in the future are increasingly
becoming software defined rather than hardware defined.
